On the last day of IBS, Matt Risinger speaks with four vendors. He tours through closed cell foam walls, which are surprisingly strong, and a conditioned attic space, a typical find in a Southern home. A handful of IBS attendees tell Risinger which of his tips have been particularly helpful, from Sugatsune hidden door hinges to flush base trim. Mark Clement from My Fix it Up Life stops by before we get a taste of Ultra Aire's latest dehumidifier. Then, Risiginer has a laugh at Panasonic's Museum of Low Performance display, which shows off three different competitor fans with incredibly low-air output. There's a little lesson to be learned here check CFM output on a fan BEFORE installing! Lastly, watch as the guys from #KeepCraftAlive talk about their Instagram popularity before the show wraps up. Thank for watching!
